A) yes you are to keep the same warband for the run of this event. Otherwise it would make the exp from each game pointless. And there is no way you can justify transfering experience between warbands since upgrades from leveling is random.
B) Unholy relic allows you to pass the first leadership based test in a game. This applies to rout tests, but if you leader had to take another leadership based test it would also get used on that. So be wary of psychology test (i.e. fear, stupidity, all alone, etc.) The relic is good for only one use per game.
C) We will not be doing three games unless people really call for it, we will meet next week and see if we can up it to two games a week. If the majority wants that then we shall go with it.
It would go without saying that the only games that count are the ones that are setup by me. If there is a reason to suspect any fudging of warband sheets I will question someone on the upgrades. For example if someone had a character that managed to level multiple times in one game his opponent would remember and I record the matches. So I will be able to check to see if the stories match up.
All equipment, warrior, and rare items are to be purchased directly after a game with your opponent present. There is no going home and deciding on whether or not to buy something for next game. If it can wait till before your next game then it can wait for after your next game.
